The

interface represents 4x4 matrices, suitable for 2D and 3D operations.**DOMMatrix**

A 4x4 matrix is suitable to describe any rotation and translation in 3D.

This interface should be available inside Web workers, though some implementations don't allow it yet.

## Constructor

`DOMMatrix()`

- Creates a new DOMMatrix object.

## Properties

*This interface inherits properties from DOMMatrixReadOnly, though some are modified not to be read-only.*

`is2D`

Read only`A boolean`

flag set to true if current matrix was initialized as a 2D matrix`isIdentity`

Read only`A boolean`

flag returning true if the current matrix is identity.`m11`

## Methods

*This interface inherits methods from DOMMatrixReadOnly.*

`DOMMatrixReadOnly.multiplySelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being multiplied by the given`DOMMatrix`

. `DOMMatrixReadOnly.preMultiplySelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the given`DOMMatrix`

being multiplied by the original matrix. `DOMMatrix.translateSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the matrix being translated by the given vector. `DOMMatrix.scaleSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the matrix x and y dimensions being scaled by the given factor, centered on the origin given. `DOMMatrix.scale3dSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the matrix x, y and z dimension being scaled by the given factor, centered on the origin given. `DOMMatrix.scaleNonUniformSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the matrix x, y and z dimension being scaled by the given factor for each dimension, centered on the origin given. `DOMMatrix.rotateSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being rotated by the given angle, with the rotation centered on the origin given. `DOMMatrix.rotateFromVectorSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being rotated by the angle between the given vector and (1,0), centered on the origin given. `DOMMatrix.rotateAxisAngleSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being rotated by the given angle and the give vector. `DOMMatrix.skewXSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being skewed along the x-axis by the given factor. `DOMMatrix.skewYSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being skewed along the y-axis by the given factor. `DOMMatrix.invertSelf()`

- Returns itself, a
`DOMMatrix`

, with its new content being the result of the original matrix being inverted. If the matrix cannot be inverted, all its components are set to`NaN`

and`is2D()`

returns`false`

. `DOMMatrix.setMatrixValue()`

- Returns itself, a
`DOMMatrix`

, with its describing the matrix representing the same transformation as the CSS`transform`

functions given in parameter.
